Blast from the Past - 1967: Hubert Upton invents analogue wearable computer
  with eyeglass-mounted display to aid lipreading
From: MIT - Brief History of Wearable Computing

Hubert Upton designed an analogue wearable computer as an aid for
lip-reading. Using high and low-pass filters, the system would determine if a
spoken phoneme was a fricative, stop, voiced-fricative, voiced stop, or
simply voiced. An LED mounted on ordinary eyeglasses illuminated to indicate
the phoneme type. The LEDs were positioned to enable a simple form of
augmented reality; for example, when a phoneme was voiced the LED at the
bottom of the glass illuminated, making it seem as if the speaker's throat
was glowing. The work was presented at the Conference on Speech-Analyzing
Aids for the Deaf, June 14-17, 1967, and was subsequently published in Upton,
H, "Wearable Eyeglass Speechreading Aid," American Annals of the Deaf, V113,
2 March 1968, pp. 222-229.
